Codó's air quality reflects the Maranhão semi-arid interior, with vehicle emissions from the BR-316 and surrounding babaçu palm, agricultural, and light industrial operations contributing local sources. Dry season burning from surrounding Maranhão agricultural and Cerrado-Caatinga transition land contributes seasonal PM2.5 variation, while the flat Maranhão sertão terrain generally allows reasonable wind dispersal on most days.
